Which cardiovascular agent is known for its brand name Lanoxin?

• A. Digoxin
• B. Nitroglycerin
• C. Verapamil
• D. Furosemide

Answer: (A)

Lanoxin is the brand name for digoxin, which is a medication used to treat various heart conditions, primarily atrial fibrillation and heart failure. Digoxin works by increasing the force of the heart's contractions and helps to regulate heart rate, making it particularly effective for patients with heart problems. Digoxin’s mechanism of action involves inhibiting the sodium-potassium ATPase pump, leading to an increase in intracellular calcium levels, which enhances cardiac contractility (the strength of heart muscle contractions) and improves symptoms of heart failure. This specific action distinguishes digoxin from the other medications listed. While nitroglycerin is used primarily for angina and to relieve chest pain by dilating blood vessels, verapamil is a calcium channel blocker that helps to lower blood pressure and control heart rate, particularly in cases of hypertension and certain arrhythmias. Furosemide, on the other hand, is a diuretic used to reduce edema and manage fluid overload in conditions like heart failure, but it does not directly improve cardiac contractility like digoxin does. Therefore, the association of the brand name Lanoxin with digoxin is key to its therapeutic use in managing specific cardiovascular conditions.
